Description and Introduction

Microprocessor Supervisory Circuits The MAX690MLP/883B is a microprocessor (μP) supervisory circuit manufactured by **MAXIM** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Manufacturer:**  
- **MAXIM** (now part of Analog Devices)  

### **Specifications:**  
- **Part Number:** MAX690MLP/883B  
- **Type:** μP Supervisory Circuit  
- **Package:** Ceramic Leadless Chip Carrier (LCC)  
- **Temperature Range:** Military-grade (-55°C to +125°C)  
- **Qualification Level:** MIL-PRF-38535 Class B (883B)  

### **Descriptions & Features:**  
- Monitors **μP power supply** and resets the system during power failures or brownouts.  
- **Precision voltage monitoring** for 5V systems.  
- **Manual reset input** for external system reset control.  
- **Watchdog timer** to detect software lockups (typically 1.6s timeout).  
- **Low quiescent current** (typically 50μA).  
- **Battery backup switching** for CMOS RAM or other critical circuits.  
- **Power-fail comparator** for early warning of power loss.  
- **High reliability** for military and aerospace applications.  

This device is designed for **mission-critical applications** requiring robust power monitoring and reset functionality.  

(Note: For detailed electrical characteristics, refer to the official datasheet.)
